  2. Variable refresh rate - Wikipedia

    en.wikipedia.org/wiki/Variable_refresh_rate

    On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown ().

    As the name suggests, DRR will lower your laptop's refresh rate to 60Hz when you're doing things like writing emails and documents and then increase it to 120Hz when inking and scrolling so that ...

  4. Refresh rate - Wikipedia

    en.wikipedia.org/wiki/Refresh_rate

    The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image.

  5. Flicker (screen) - Wikipedia

    en.wikipedia.org/wiki/Flicker_(screen)

    The exact refresh rate necessary to prevent the perception of flicker varies greatly based on the viewing environment. In a completely dark room, a sufficiently dim display can run as low as 30 Hz without visible flicker. [citation needed] At normal room and TV brightness this same display rate would produce flicker so severe as to be unwatchable.

    Front and rear views of the TVM MD-3 cathode-ray tube monitor (Enhanced Graphics Adapter era). Note the DE-9 connector, cryptic mode switch, contrast and brightness controls at front, and the V-Size and V-Hold knobs at rear, which allow the control of the scaling and signal to CRT refresh rate synchronization respectively.

  7. FreeSync - Wikipedia

    en.wikipedia.org/wiki/FreeSync

    LFC helps ensure that when the framerate of a game is running below the minimum supported refresh rate of a display, the frames are displayed multiple times so the framerate remains in the supported refresh rate of the display and smooth gameplay is maintained. [14] AMD FreeSync Premium Pro adds luminance and wide color gamut requirements. [5]

  8. Screen tearing - Wikipedia

    en.wikipedia.org/wiki/Screen_tearing

    That eliminates the stutter that occurs as the rendering engine frame rate drops below the display's refresh rate. [4] Alternatively, technologies like FreeSync [5] and G-Sync [6] reverse the concept and adapt the display's refresh rate to the content coming from the computer. Such technologies require specific support from both the video ...

  9. Scan conversion - Wikipedia

    en.wikipedia.org/wiki/Scan_conversion

    In a 100 Hz/120 Hz analog TV, there is a scan converter circuit which converts the vertical frequency (refresh rate) from standard 50/60 Hz to 100/120 Hz to achieve a low level of flicker which is important in large screen (high inch) TVs. An external TV card receives the TV signals and converts them to VGA or SVGA format to display on monitor.
